T0 @ZZ whom, t may concern:

Re it known that I, SAMUEL TURNER, of the city and county of New York, in the State of New York, have invented a new and useful Improvementin Apparatus forSupplying Liquid Fuel to Burners, of which the following is a specification.

My invention relates to an improvement in apparatus for supplyingliquid fuel to a burner and more particularly to apparatus for feed` ing a fluid hydrocarbon, either alone or mingled with water.

In feeding a liquid hydrocarbon, such for example as crude kerosene oil, to a burner, it has been found that when the burner or the coil in proximity tothe burner becomes highly heated by the flame issuing from the burner, there is a tendency of the vaporized or gasified oil to blow in puffs which are liable to extinguish the flame at the burner. I have found that this tendency to puff can be avoided by flushing the oil feed pipe with oil under sufficient head to prevent the pent up gas from relieving its pressure backwardly or in the direction of the oil-feed pipe. I have further found that the oil feed pipe may be flushed with oil from the oil supply by providing the said pipe with an air vent at a point below the supply tank or at or below the point where the oil supply enters the oil feed pipe.

My present invention therefore consists in providing the oil feed pipe, which conducts the oil from the supply tank to the burner,

with an air vent at or below the point where the said oil supply enters the feed pipe.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure l represents, in elevation, partly in section, an oil feed pipe in connection with a water feed pipe and their respective oil and water supplies leading to the burner beneath a coil within a heater. Fig. 2 represents a similar view, in which the oil alone is fed to the burner; and Fig. 3 represents the airvent formed by means of a pipe extending through the oil supply tank, instead of exterior thereto.

A represents the oil tank, shown in the present instance supported upon a bracket B made vertically movable along a support O,

for the purpose of increasing or diminishing the head under which the oil is fed.

D represents the oil feed pipe leading from the bottom of the oil supply A to a connection d with a water feed pipe E; and thence to a coil F within a heater G, the said coil F terminating at its lower end in a portionf, provided with a nipplef through which the vaporized oil escapes to be ignited.

The water feed pipe E connects with the bottom of the water supply tank Il, provided in the present instance with a filling pipe h and with adischarge pipe h and air vent pipe h2, the several pipes being provided with stop cocks of any well known or approved form, located in convenient positions for cutting off and permitting the liow of liquid or air therethrough, as may be desired.

The air vent pipe I connects with the oil feed pipe D ata pointjust below the bottom 0f the oil supply tank A and extends thence laterally and upwardly to a point above the level of the oil within the supply tank A.

In the form shown in Fig. 2, the oil tank A is provided with an oil feed pipe D', leading to the coil F within the heater G', without any connection with a water supply, the arrangement being that adapted for burning a fluid hydrocarbon without mixture therewith of water. The feed pipe D is here sho-wn as provided with an air vent pipe I' leading from it at a point just below the bottom of the tank A and upwardly to a point above the surface of the oil supply within the tank A in amanner quite similar to that shown in Fig. 1.

In Fig. 3, the air vent pipe I2, instead of branching from the oil feed pipe at a point below the .bottom of the tank A', extends downwardly through the tank A and enters the receiving end of the pipe D at the bottom of the tank A.

In operation, as the oil leaves the supply tank A or A and passes along down the feed pipe, the air from said feed pipe will escape through the vent pipe I, I or I2, therebypermitting the oil feed pipe to become filled with oil and the said feed pipe will continue filled as long as the supply in the-tank A or A holds out. This will keep such a head of oil at all times between the oil supply tank and the hot IOO burner or coil that the expanding gases within the burner or coil Will not be able to relieve their pressure against such body of oil and the pressure at the burner will continue, as experience has proven, steady and the size of the flame may be regulated with great accuracy by increasing or diminishing the feed ofl the oil by a suitable stop cock d in the oil feed pipe.

1. The combination with an oil feed pipe for directing the oil from an oil supply to a burner, of an air vent pipe communicating with the said oil feed pipe at or below the point where the oil feed pipe receives its supply, substantially as set forth.

2. The combination with an oil feed pipe, a water feed pipe and a pipe into which the said oil and Water feed pipes merge for conveying mingled Water and oil from suitable supplies to a burner, of an air vent pipe communicating with the oil feed pipe at or below the point Where the said oil feed pipe receives its supply, substautially as set forth.

SAMUEL TURNER.
